A bluefag is a person (usually female, but there are male bluefags too) who tries to sway a conversation into one about eye color. After she does that, she then proceeds to talk about her own eyes, and fishes for compliments from the people she's talking to.

Bluefags usually talk about their eyes to distract other people from how ugly the rest of their face is.

Note: Bluefags represent an extremely small percentage of people with blue eyes. Having blue eyes does NOT make you a bluefag; bragging about them does.

Bluefag: What color are your eyes?

Regular person: Brown.

Bluefag: Well, my eyes are aqua-blue with green speckles and a yellow outline.
